How to Calibrate a Gilair Plus Air Sampling Pump Using BIOS Defender 520: Step-by-Step Guide

The Bios Defender 520L by Mesa Labs is a primary liquid-free gas flow calibration standard offering a low-flow measurement range of 0.005–0.5 LPM (5–500 ml/min), providing traceable volumetric flow verification without the need for bubbles or liquids. Its pushbutton interface allows users to set engineering units, temperature compensation, and continuous or burst measurement modes in seconds, and it simultaneously records ambient temperature and pressure for a complete audit trail. It is the ideal calibration standard for low-flow personal air sampling applications including sorbent tube, passive badge, and low-volume media sampling in industrial hygiene programs.
